Catching up with a previous post, I was again prompted to answer the same question.

Well, this time I choose “More than two flights (more than one return flight)” and this is what they got for me:

It’s like, I accepted the licensing terms without reading it and its mentioned there:

“WordWeb free version may be used indefinitely only by people who take at most two commercial flights (not more than one return flight) in any 12 month period.”

It may seem silly to you but these guys at WordWeb have an explanation for such a deal:

“…the WordWeb licensing is just reflecting the current huge under-pricing of air travel. Every time you fly you are not paying the cost to the environment (and hence other people); in economics terms climate-changing emissions are an important externality leading to a market failure. WordWeb is trying to slightly increase the cost of flying via its licence to correct for this anomaly. If and when air travel is charged correctly to reflect the total cost, which is much the most efficient solution, the WordWeb licence will be changed to a more sensible economic model.

The licence also has the advantage that people who cannot easily afford to pay can use the program for free. If you can afford to fly, so that you do not satisfy the licence, you can afford to buy the program.”

Nice thoughts, but still makes me realize the number of software applications that I have installed without reading the license! Hmm…
